# SKTileGroupRule

Rules that describe how various tiles should be placed in a map.

## Declaration

```swift
class SKTileGroupRule
```

## Overview

Overview When a tile is filled in a tile map, the tile group rule defines how neighboring tiles are populated based on adjacency rules. A rule with multiple definitions uses the placement weights of the definitions to randomly select which to use.
